CONDUIT.

SPECIFICATION forming part of Letters Patent N o. 681,158, dated August 20, 1901.

l Application filed July 6, 1901. Serial No. 67,376. (No model.)

To all` whom, it may concern:

Be it known that I, CHAnLEs A; WANNER,

a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Conduits, of which the following is a specification.

i The object of my invention is to so contions can be readily alined and several series of sections can be assembled in line within a ,y trench, as fully described hereinafter.

In the accompanying drawings, Figure 1 is 1 l f l a perspective View of a section of a conduit,

illustrating my invention. Fig. 2 is a perspective view showing a series of sections assembled. Fig. 3 `is a sectional view on the line 3 3, Fig. 4. Fig. 4 is a longitudinal sec# asf " as shown in Figs. 2, 3, and 4, the lugs of one y tional View of thev conduit shown in Fig. 3, f 2O tions of my invention.

and Figs. 5, 6, and 7 are views of modifica- A is a conduit-section made of clay and baked in the ordinary manner. In the presy j ent instance this conduit haspfour compartments a, formed by partitions b; but it will be understood that any number of compartments may be formed as desired.

Two sides of the conduit have longitudinal j l groovesd,preferably extending the full length 3.o other two sides of the conduit are lugs e.

of the conduit, as shown in Fig. 1, and on the These lugs are preferably short and situated some distance from each end of the conduitsection.

When the several conduits are assembled conduit-section enter the grooves formed in the sides of the other conduit-sections, and if the sections are assembled, as shown in Fig. 2,`so that the joints will be staggered, onelug of each abutting section will enter a groove of a single adjoining section near the center. By this arrangement the sections can be assembled and will readily lit whether j 45..

the sections are warped during the baking or not, as it is essential that the abutting `1 ends of the sections should be in line, so that wires passed through the conduits will not catch on the edges of the conduits, although in order to prevent the catching of the wires j in passing through the conduitsl the ends are beveled, as shown in Fig. 4, in the ordinary manner.

In Figs. 1, 2, 3, and 4 I have shown each section having a groove on one side and lugs on theA opposite side, with a groove at the top and lugs on the bottom, so that the sections can be laid one upon another,with the grooves of all the sections at the top; but the sections may be made, as shown in Fig. 5, with the lugs opposite each other.

In some instances there may be more than two lugs on the conduit, and the lugs may be of any length desired, depending greatly upon the character of the material of which the conduit is made, and in some instancesa single lug may be used, if desired, and this lug can be at the point where the joint be-. tween two sections comes, so that the lug on one section will aline the ends of two abutting sections; but I prefer the construction shown in Fig. 1.

Fig. 6 is a modification of my invention in which two conduit-sections differing in shape are used, one section having longitudinal ribs or projections f at the corners, and the other section having its corners beveled at g for the i reception of the ribs of an adjoining section.

In some instances a single conduit-section may be used, as shown in the modification Fig. '7, in which diametrically opposite corners have projecting ribs and the other corners are beveled.

Each of the modifications shown in Figs. 6 and 7 have the lugs and grooves shown in Fig. 1.

I claim as my inventionj 1. A conduit having grooves on two sides and lugs on the other two sides, said lugs being shaped to enter grooves in the adjoining conduit-sections, substantially as described.

2. A conduit quadrangular in cross-section having in one side and in the top a longitudinal groove and having at the other side and IOO being shaped to enter the grooves of adjoin- In testimony whereof have signed my ing conduits, substantially as described. name to this specitication in the presence of 4:. A conduit quadrangular in cross-section two subscribing witnesses. having two longitudinal grooves and lugs, 5 and having longitudinal ribs at two or more Witnesses:
